ABSTRACT:
Apparatus is disclosed for accomplishing electrophoresis in an automated manner. A supported electrophoretic medium, having been implanted with sample to be analyzed, is moved through a chamber wherein the electrophoresis takes place. The apparatus comprises an electrophoresis separation chamber containing a pair of elongated electrolyte wells, electrolyte contained within the wells, electrodes disposed within the electrolyte and connectable to an appropriate source of power, and a wicking arrangement communicating with each of the electrolyte wells to provide a continuous electrical contact zone. A moving belt arrangement is provided capable of moving support strips having the electrophoretic medium disposed thereon from one end of the separation chamber to the other while keeping one end of the strips in electrical contact with one wick and the opposite end in electrical contact with the second wick whereby a continuous electrical field is applied across the strips and electrophoretic medium as they move through the separation chamber and the electrophoresis separation is caused to take place. In the preferred embodiment, the strips containing the electrophoretic medium are releasably carried by a flexible backing material so that the strips can be moved into and through the separation chamber individually or in groups.
